What artery supplies the inferior cerebellar peduncle?
posterior inferior cerebellar artery 1
The inferior cerebellar peduncles predominantly receive their arterial blood supply from branches of the posterior inferior cerebellar artery 1-3.
What passes through inferior cerebellar peduncle?
The inferior cerebellar peduncle, or restiform body, carries primary afferent fibers from the structures close to it: the medulla, spinal cord, and cranial nerve VIII. Thus spinocerebellar, medullocerebellar, and vestibular fibers pass through the inferior peduncle.
What supplies the inferior cerebellum?
The cerebellum is mainly supplied by the following three long cerebellar arteries arising from either the vertebral or basilar artery: the posterior inferior cerebellar artery (PICA), the superior cerebellar artery (SCA), and the anterior inferior cerebellar artery (AICA).
What is the blood supply to the brainstem?
The vertebral and basilar arteries supply the brainstem and cerebellum.
What passes through the superior cerebellar peduncle?
The superior cerebellar peduncle conveys selective afferents to the cerebellum and carries extensive efferents from the globose, emboliform, and dentate nuclei to the red nucleus and ventrolateral thalamus for regulation of the rubrospinal and corticospinal UMN systems.
Which spinocerebellar tracts pass thru the inferior cerebellar peduncle to enter the cerebellum?
The rostral spinocerebellar tract is like the ventral spinocerebellar tract but the difference is that it conveys information about the upper limbs from the Golgi tendon organs. It is an ipsilateral pathway and the information passes to the cerebellum via the inferior cerebellar peduncles.
What does posterior inferior cerebellar artery supply?
The posterior inferior cerebellar artery (or PICA) is an artery that provides blood flow to the cerebellum, a part of the brain located behind the top of the brain stem, which helps with functions related to movement and coordination.
Where does posterior inferior cerebellar artery supply?
The PICA supplies the medulla, the choroid plexus and tela choroidea of the fourth ventricle, the tonsils, the inferior vermis, and the inferior aspects of the cerebellar hemispheres 1, 7.
What does the posterior inferior cerebellar artery supply?
The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. It is one of the three main arteries that supply blood to the cerebellum, a part of the brain.
What does the anterior inferior cerebellar artery supply?
The anterior inferior cerebellar artery supplies the middle cerebellar peduncle, lower lateral pons, anteroinferior surface of the cerebellum, flocculus and the choroid plexus of the lateral ventricle.
